  • Patent number: 7996137
    Abstract: In a method of changing the trigger threshold of a brake stand-by function of a vehicle brake, the brake stand-by function generates brake pressure in wheel brakes without application of a brake pedal. The trigger threshold value for the brake stand-by function is determined by the following steps: a) determining an average return speed of an accelerator pedal; b) changing the trigger threshold value for the brake stand-by function depending on the determined average return speed of the accelerator pedal. The method allows reducing the number of spurious releases of the brake stand-by function, which a sportive driving style brings about. In another embodiment of the method, the position of the accelerator pedal is used to change the trigger threshold value for the brake stand-by function.

  • Patent number: 7996136
    Abstract: A system and method for monitoring brake performance, in particular, in motor vehicles, are provided. The braking distances specific to each vehicle wheel are determined and compared using an electronic control unit. If a wheel exhibits a longer than average braking distance, insufficient braking is identified and is displayed by means of a display device.

  • Patent number: 7987054
    Abstract: A method is disclosed that uses (a) source-receiver reciprocity and (b) a method such as ISR DMO (U.S. Patent Application Publication No. 2006/0098529) that allows reconstruction of densely sampled gathers at arbitrary surface locations, to efficiently predict multiple reflections, either surface related or interbed multiples, in seismic data. For each reconstructed gather and each output (field) trace, two traces are extracted corresponding to the field source and receiver positions of the output trace, then they are convolved and the convolution result is added (summed) to that obtained by applying this procedure to previously reconstructed gathers. The efficiency results from the fact that the convolutions are performed by looping over all traces for each “bounce” point, with the outer loop being over bounce points. Once all the reconstructed gathers are processed, multiple predictions are obtained for the whole survey by conventional means.

  • Patent number: 7987034
    Abstract: The invention concerns a method for controlling automatic transmission (3) of a vehicle comprising an engine (2) driving the transmission (3) which consists in: detecting a downhill situation of the vehicle, and selecting a transmission ratio so that the engine absorbs energy, storing a longitudinal speed of downhill start (Vmin) when the vehicle starts going downhill, and while the vehicle is running downhill, comparing the current speed (V) of the vehicle with the downhill start speed (Vmin) such that the current speed (V) exceeds the downhill start speed (Vmin) by a predetermined difference (VS), then controlling the transmission to trigger downshifting.

  • Patent number: 7986587
    Abstract: A method of imaging the Earth's subsurface using passive seismic emissions includes detecting seismic signals originating from within the Earth's subsurface over a selected time period using an array of seismic sensors deployed proximate the Earth's surface. Hypocenters of seismic events in the subsurface are determined from the detected signals. Seismic signals detected at selected ones of the seismic sensors are cross-correlated to signals detected at other selected ones of the seismic sensors. The cross-correlated signals are processed to obtain a reflectivity series at a geodetic position of the selected one of the seismic sensors. A spatial distribution of at least one seismic property in the subsurface is determined using the determined hypocenters and the reflectivity series.

  • Patent number: 7986588
    Abstract: The method for exploring desired characteristics of a subsurface sector, having at least one resonant frequency, is based on selectively transmitting suitable narrowband energy waves into the subsurface sector, thereby producing narrowband signals reflected off the subsurface sector. The transmitted narrowband energy waves can be selectively and optimally adjusted in real time so as to provide optimum illumination of the desired characteristics from the explored sector.

  • Patent number: 7986586
    Abstract: Seismic data are obtained for each seismic source activation in a marine streamer and for each frequency, after being transformed to a spectral domain. An iterative conjugate gradient scheme, using a physically-based preconditioner, is applied to the transformed seismic data, to provide a least squares solution to a normal set of equations for a deghosting system of equations. The solution is inverse-transformed back to a space-time domain to provide deghosted seismic data.

  • Patent number: 7983828
    Abstract: A stepwise brake control is automatically performed when TTC obtained according to a relative distance and a relative speed between a vehicle and an object is lower than a predetermined value. For example, a brake force or a brake reduction speed is gradually increased over a plurality of stages in time series. Moreover, the affect of speed change control to the automatic brake control is removed. Alternatively, automatic brake control is supported by the speed change control. Alternatively, the friction coefficient state is estimated, and the brake force or the brake speed reduction is adjusted according to the estimated result. Alternatively, an auto-cruse function is invalidated at least the final stage. Alternatively, when the brake force or the brake speed reduction generated by a brake operation by a driver is greater than the brake force or the brake speed reduction generated by the brake control means, the brake operation by the driver is handled with a higher priority than the stepwise brake control.

  • Patent number: 7983842
    Abstract: There is a need for improving the accuracy of estimating a gain error for an angular velocity sensor. An error estimation section and a correction section are provided as well as a gyroscope that detects an angular velocity of a vehicle. The error estimation section assumes the gain error of the gyroscope to be a state quantity and finds an estimated value for the gain error using a Kalman filter. Based on the gain error found by the error estimation section, the correction section corrects a gain correction amount used for gain correction of values detected by the gyroscope. The correction section corrects the gain correction amount dedicated to right turn based on the gain error found by the error estimation section when the vehicle is assumed to turn right. The correction section corrects the gain correction amount dedicated to left turn based on the gain error found by the error estimation section when the vehicle is assumed to turn left.
